Hi Michael T
There is a little problem with SU Exporter for OpenSpace3D
You can't explose a scene with some objets From Sketchup so you must import one by one !

So best if you have object multiples : Moi (obj) --> Blender --> OpenSpace3D
or Moi (SKP) --> SKetchup (Collada) --> Blender --> OpenSPace3D ;)

Thanks Pilou. Sorry to take so long to get back to you. Went on family campout :-)

I'll check it out.

Thanks,

Michael T.

Here the last export Ogre for SKetchup
Now Groups and Components can be exploded but not yet simple objects ;)

A little video : export Sketchup to OpenSpace3D + Dynamic Component simulation ;)
Sorry it's in French but it's visual ;)
